My brother got this movie and I watched it yesterday. I haven't seen The Ring but Ringu is the original version. The movie is in DD/Japanese Language/English Subtitled.
This movie is one of the scariest movie I've ever seen. The last movie that really scared the crap out of me was The Others. I think this one's creepier.
I don't have 5.1 yet so I watched the movie in 2.1 using my XBox as a DVD player. The sound quality is very good and the dynamics made me jump a few times. The bass was also powerful.
Picture quality is above average. The tinted quality used to show scenes that happened in the past was very effective.
If you feel like getting scared check out Ringu. It kept me on the edge of my seat for two hours.
